The reef hobbyist's choice for monitoring aquarium pH. Salifert pH Test Kit is accurate to approximately 0.2 pH units so you can monitor minute pH fluctuations. A stable, high pH level is crucial for healthy marine aquariums, especially reef aquariums where low pH can affect the growth of corals and coralline algae. 50 tests per kit. For marine aquariums only.

Range: pH 7.4 - 8.6.

INSTRUCTIONS

Fill the test vial with 5ml of water.

Add to this, 6 drops of the pH reagent and swirl gently for 10 seconds.

Compare colors by looking through the side. For this purpose, hold the white part of the color chart against one side of the test vial and look through the opposite side. Best results are obtained by using natural daylight.

If the color is somewhere between two values, then the pH is also in between those values.

In case the pH is too low, the alkalinity might be too low. However, never increase the alkalinity to a value higher than 12 dKH or 4.3 meq/L.

Don't take the quality of your tap water for granted. If you draw your water from a well, nature may not be providing you the perfect balance. If you are using tap water from your municipal department, it likely includes minerals and additives.

Serious hobbyists know that the best way to measure the salinity and specific gravity of aquarium water is to use a refractometer. These precision optical instruments are incredibly accurate even at very low salt levels, and are equally easy to use.

Testing your water parameters is an important method of foreseeing problems in your aquatic ecosystem before they result in catastrophe. Luckily, tools that were once only accessible (and affordable) to advanced hobbyists have since become simpler.

difficult to read results
because of the wide range of results from test to test, i use 2 sometimes 3 tests from different manufacturers, depending on how critical the water parameter is, then average the results. but with this product, the color card isnt close to actual results. so i discarded it and went with another supplier. but in fairness to salifert, i trust the other test products they make and regard them as an excellent product. water parameters are everthing in a marine set up.
